Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to an adaptive profile clamp. Background Technology

[0002] Fixtures are commonly used auxiliary tools in the field of machining and manufacturing. They are mainly used to clamp profiles to maintain their posture, and then use processing equipment to process the profiles to improve processing accuracy. Aluminum profiles are increasingly widely used in industry. When processing profiles, due to their application and design requirements, it is necessary to clamp the profiles to keep them in a stable position, and then mill their end faces.

[0003] In existing equipment, the most common profile clamping device is to set up several cylinder clamping parts on the worktable. The cylinder action drives the lower pressure plate to press down on the profile to restrict and fix the profile on the worktable. However, the surface shape of some profiles is not flat. When the cylinder directly performs the clamping action, the uneven parts of the profile surface are easily subjected to uneven clamping force and deformed, resulting in low profile processing accuracy or even scrap.

[0025] 4. Profiles. Detailed Implementation

[0026] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0027] like Figure 1As shown, this application proposes an adaptive profile fixture, which includes a worktable 1. The worktable 1 has several clamping areas arranged parallel to each other along a first direction. The clamping areas are used to place profiles 4. The clamping areas are circumferentially arranged with clamping mechanisms 2, which are used to limit the horizontal displacement of the profiles. A floating pressing mechanism 3 is arranged between two adjacent sets of clamping areas, which is used to limit the vertical displacement of the profiles. The clamping mechanism 2 and the floating pressing mechanism 3 cooperate with each other to stably constrain the profiles 4 on the worktable 1 so that the profiles 4 can be milled.

[0028] like Figure 1-2 As shown, the clamping mechanism 2 includes an end clamping member 21. The end clamping member 21 includes a first abutting portion and a first clamping portion disposed opposite each other along a second direction, respectively disposed on both sides of the clamping area along the second direction, for limiting the horizontal displacement of the profile in the second direction. The first abutting portion includes an abutting end plate 211, and the first clamping portion includes a first clamping block 212 and a first clamping cylinder 213 that drives the first clamping block 212 to move closer to and further away from the abutting end plate 211. Preferably, a support plate 214 is disposed on the upper part of the abutment end plate 211, and a guide post 215 is disposed through the support plate 214 along the second direction. An abutment block 216 is disposed at one end of the guide post 215 near the first clamping part, and a limit block 217 is disposed at the other end, so that the guide post 215 can move laterally relative to the support plate 214 without disengaging from the support plate 214. A spring 218 is circumferentially sleeved on the guide post 215, and the two ends of the spring 218 are restricted between the support plate 214 and the abutment block 216. During the clamping process of the profile, the abutment end plate 211 provides a clamping reference surface, the abutment block 216 abuts against the profile, the guide post 215 adaptively moves laterally according to the shape of the side end face of the profile, the spring is compressed, and a reverse force is applied to the profile to achieve clamping of the profile in the second direction.

[0029] like Figure 1 and 3 As shown, the clamping mechanism 2 further includes a side clamping member 22. The side clamping member 22 includes a second abutment portion and a second clamping portion disposed opposite to each other along a first direction, respectively disposed on both sides of the clamping area along the first direction, for limiting the horizontal displacement of the profile in the first direction. The second abutment portion includes an abutment side plate 221, and the second clamping portion includes a second clamping block 222 and a second clamping cylinder 223 that drives the second clamping block 222 to move closer to and further away from the second abutment portion. Preferably, the upper and lower ends of the side end face of the second clamping block 222 near the abutment side plate 221 are rotatably connected to movable abutment blocks 224 via a rotating shaft 225. During clamping, the movable abutment blocks 224 can be adaptively adjusted according to the shape of the profile side end face.

[0030] like Figure 1 , 4As shown in Figure 5, the floating pressing mechanism 3 includes a floating connecting rod 31 and a first lifting cylinder 32 that drives the floating connecting rod 31 to rise and fall. The two ends of the floating connecting rod 31 extend above the clamping areas on both sides and are respectively equipped with floating pressure blocks 33. The push rod end of the first lifting cylinder 32 is connected to an insert block 34. The insert block 34 and the floating connecting rod 31 are rotatably connected by a transverse pin 35. The transverse pin 35 extends along the second direction. There is a first gap 36 between the two sides of the insert block 34 and the floating connecting rod 31 along the first direction, so that the two ends of the floating connecting rod 31 can float up and down in the vertical direction relative to the insert block 34 to make adaptive adjustments according to the height of the profiles on both sides.

[0031] like Figure 1 , 4 As shown in Figure 5, floating grooves 311 are provided at the bottom of both ends of the floating connecting rod 31. The cross-section of the floating groove 311 along the first direction is a circle larger than half a circle. The floating pressure block 33 includes a snap-fit ​​part 332 and a pressing part 331 connected to the bottom of the snap-fit ​​part 332. The snap-fit ​​part 332 is snapped into the floating groove 311 and can rotate within the floating groove 311 along the first direction. The pressing part 331 is pressed against the upper end face of the profile and fits against the uneven surface of the profile. The cross-section of the snap-fit ​​part 332 along the first direction is a circle larger than half a circle. The diameter of the cross-section of the snap-fit ​​part 332 is larger than the chord length of the cross-section at the lower opening of the floating groove 311, so that the snap-fit ​​part 332 is snapped into the floating groove 311 in the vertical direction and can rotate relative to the floating groove 311 along the first direction. The first lifting cylinder 32 drives the floating connecting rod 31 to press down. The two ends of the floating connecting rod 31 are adjusted up and down according to the height of the profile. The pressing part 331 is adjusted by the pressing angle according to the concavity and convexity of the pressing contact part of the profile, so as to prevent hard extrusion of the profile during the pressing process, thereby causing deformation.

[0032] like Figure 1 , 4As shown in Figure 5, preferably, a limiting screw 37 is provided between the floating pressure block 33 and the floating connecting rod 31 to limit the displacement of the floating pressure block 33 relative to the floating connecting rod 31 in the second direction. The floating connecting rod 31 has a limiting groove 312 at the upper part corresponding to the floating groove 311, and the limiting groove 312 is connected to the floating groove 311. The limiting screw 37 passes through the floating pressure block 33 from bottom to top, with its upper end protruding from the locking part 332 and inserted into the limiting groove 312 to prevent the floating pressure block 33 from moving horizontally and disengaging from the floating groove 311. The specific assembly process is as follows: slide the snap-fit ​​part 332 of the floating block 33 from one side of the floating groove 311 along the second direction into the floating groove 311, and then screw the limiting screw 37 upward from the bottom of the floating block 33 so that the upper part of the limiting screw 37 is placed in the limiting groove 312, so as to realize the connection between the floating block 33 and the floating connecting rod 31 and the floating block 33 can rotate relative to the floating connecting rod 31 in the first direction.
